Inflatable welding enclosure

02 November 2018

Welding applications within industries such as the Aerospace, Additive Manufacturing and F1 Racing as well as Medical, Pharmaceutical, Semiconductors and any other company that needs super clean welding joints, have a requirement of absolute cleanliness and smoothness of surfaces, ensuring each weld is mechanically stable and free from oxidation.

Titanium is often the metal of choice for such joints and being a reactive metal, must be shielded with argon during welding to protect the molten metal from oxygen, moisture and nitrogen. It is inevitable that some shielding methods will occasionally fail to fully protect the weld, which may lead to a loss of corrosion resistance properties and a rejected weld.

Reliable exclusion of reactive gases in the welding environment is guaranteed when using a low cost Flexible Welding Enclosure®, together with a Weld Purge Monitor® designed and manufactured from Weld Purging Experts Huntingdon Fusion Techniques HFT®, to achieve and show oxygen levels as low as 10 parts per million.

Size for size, Flexible Welding Enclosures® cost considerably less than a metal glove box or a vacuum system. A vacuum system is not necessary to obtain a very fast purging time down to a few ppm of oxygen. The Welding Enclosures are ideal for small production quantities of items that need total gas coverage, as well as single large items with critical joints.

A combination of translucent material and optically clear sheet is used depending on the viewing requirements of the customer. Large access zips are fitted to each enclosure and additional entry points for operators’ gloves can be provided.
